The former Stromgodset boss insists his side will be ready for the task in hand following their pre-season trip to Austria where they were unbeaten in four games.
"They are big games but that is why I came here, to get the possibility to play in Europe," he said. "This is the first and I am looking forward to it.
"We have been training well for three weeks and it has come quick but it is good to get started and of course Champions League matches are special.
"We have prepared well, we have played four games and I think we have had a lot from them. Of course there is a lot to improve still but we are ready for the game."
Deila shrugged off a question about a weight of expectancy on him, saying: "I have been in football for many years and everything in football is about winning.
"There is always more pressure in bigger clubs but you also have much better players so this is a big opportunity to achieve what you want to do. Celtic wants to win trophies and I want to win trophies.
"I know I have good footballers here. If I can get them to feel good then we are going to win matches."
